SPECIFICATION forming part of Letters Patent No. 596,482, dated January4, 1898.

Application led March 10, 1897. Serial No. 626,813. (No model.)

To all whomV it may concern:

Be it known that I, RICHARD L. COBURN, a citizen of the United States,residing at Roanoke, in the county of Roanoke and State of Virginia,have invented a new 'and useful Lamp-Burner, of which the following is aspecification.

The purpose of the present invention is to enable lamp-burners to bereadily cleaned in the event of fouling from any cause, to' prevent theoverheating and the consequent burning of the wick, and to increase thequality of the light.

With the foregoing ends in view the invention consists, primarily, of aburner having a detachable and separable wick-tube, the latter forconvenience being composed of sections which are hinged together, so asto prevent their accidental misplacement and insure their registeringwhen placed together.

The invention also consists in combining with the separable wick-tube adrum through which the air is caused to circulate, thereby cooling theWick and increasing the illuminating qualities of the light by attaininga more perfect combustion of the oil when the wick is-lighted.

The improvement also consists of the novel features and details ofconstruction, which hereinafter will be more particularly set forth,illustrated, and finally embodied in the subjoined claims.

For a full understanding ofthe merits and advantages of the inventionreference is to be had to the accompanying drawingsand the followingdescription.

The improvement is susceptible of various `changes in the form,proportion, and t-he minor details of construction Without departingfrom the principle or sacrificing any of the advantages thereof, and toa full disclosure of the invention an adaptation thereof is shown in theaccompanying drawings, in which*- Figure 1 is a vertical central sectionof a lamp-burner embodying the essential features of this invention.lFig. 2 is a side elevation, parts being broken away. Fig. 3 is a detailperspective view of the gallery inverted, the wick-tube and partsconnected directly therewith being omitted. Fig. 4 is a detailperspective view of the wick-tube and the parts having direct connectiontherewith.' Fig. 5 is a detail perspective view of the parts shown inFig. 4, showing the sections of the wicktube open and the parts of thedrum separated.

-in its sides at diametrically opposite points with bayonet-slots 4, thelower portions of the collar separated by the said bayonet-slots beingstrengthened and braced by looped stays 5, spanning the slots andsecured at their ends to the portions of the collar bordering thereon.

The wick-tube is composed of complementary sections 6 and 7, which areseparable and hinged together at one edge, whereby the sections arecaused to register when closed and are prevented from being lost ormisplaced when separated or open. Each of the sections is flanged at itslongitudinal edges or sides to retain the wick in place and preventrelative lateral movement of the sections when assembled, and theseflanged edges fit closely, so as to prevent any leaking or wasting ofthe oil.

A drum or chamber surrounds the wicktube and consists ofsimilarly-formed parts 7a of semicircular outline and closed on allsides, the top closures or plates being perforate to provide for theescape of the heated air, and the outer sides having openings 8 for theentrance of air to keep the wick cool when the burner is lighted, saidair circulating through the respective parts of the drum or chamber andpassing out through the upper perforate plates thereof. Lugs 9 areprovided at the sides of the drum or chamber at diametrically oppositepoints,and are adapted to cooperate with the\bayonetslots 4 to securethe wick-tube and. drum to the gallery IOO of as much strain aspossible, the drum is provided with a series of supports ll concentrictherewith and adapted to engage atftheir upper ends with the bottom sideof the gallery, thereby bracing the gallery and enabling it to resistthe strain to which it is subjected when forcing the lamp-chimneythereon between the holders.

The wick-raising mechanism is applied to a section or part of the drumand consists of the usual shaft l2 and spur-wheels 13, secured theretoand projecting across the wickspace of the wick-tube, so as to engagewith the wick and move the latter up or down, according to the directionof turning the shaft. The drum aords a convenient means for housing thespur-wheels and the inner end portion of the shaft, and the section 7 ofthe wick-tube is slotted, as shown, to admit of the free operation ofthe spur-wheels, as will be readily understood. In the event of theburner fouling the wick-tube and `drum can be readily detached andparted to admit of thel wick being removed or placed in position or theobstructing matter removed, after which the wick-tube can be placed inposition and the burner restored to an operative condition.

Having thus described the invention, what is claimed as new is 1. In alamp-burner, the combination of a one-piece gallery or like support, anda wicktube having detachable connection with the gallery or support andcomposed of separable 2. In a lamp-burner, the combination of aone-piece gallery or like support, and a wicktube having detachableconnection therewith and composed of complementary sections hingedtogether at one edge and having their longitudinal edges iianged andheld closed by the gallery when the parts are fitted together,substantially as and for the purpose set forth.

3. In a lamp-burner, the combination of a one-piece gallery or likesupport, a wick-tube having detachable connection therewith and composedof separable sections which are held together by the gallery, and a drumcomposed of corresponding parts each applied to a corresponding sectionof the wick-tube and provided with openings for the circulation therevthrough of air, substantially as set forth.

4. In a lamp-burner, the combination of a gallery or like support, awick-tube detachably connected therewith and provided with a drum, and aseries of supports concentric with the drum and connected therewith attheir lower ends, and having their upper eX- tremities spreading so asto engage with the gallery at points distant from the sides of the drum,substantially asset forth for the purpose described.

5. Alamp-burner comprisin g a gallery having a depending collar formedat diametrically opposite points with bayonet shaped slots, a wick-tubecomposed of complementary sections hinged together, a sectional drumsecured to the respective sections of the wick-tube and provided withopenings for the circulation of air therethrough, lugs at the outersides of the parts of the drum and adapted to cooperate with theaforesaid bayonet-slots, supports having connection with the drum andadapted to engage with the gallery, and a wick-raising mechanism appliedto one of the parts of the drum, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in l the presence of two witnesses. y
